Who We Are

Arrow Tight Waterproofing has spent years earning a reputation in Lexington for showing up when a basement is taking on water and not leaving until it's actually fixed.

Every technician on our roster is Waterproofing-certified and licensed in SC, trained specifically in hydrostatic pressure diagnosis, drain tile installation, and structural crack classification — not general handyman work rebranded as waterproofing.

A basement filling with water doesn't wait for a convenient appointment, so our dispatch model is built around same-day response for active seepage in Lexington.

Beyond the repair itself, we document every diagnostic finding with photos and moisture readings, so you understand exactly what was found and why a given system was recommended.

Warning Signs You Shouldn't Wait On

Most serious foundation problems start small and quiet — here's what to watch for before a minor issue becomes a structural one.

A musty smell that returns no matter how often you clean the basement.

White, chalky staining on block or poured concrete walls — a mineral deposit called efflorescence.

Sticking doors on the ground floor are one of the more overlooked signs of a shifting foundation.

Even a crack thinner than a coin can be an active entry point once hydrostatic pressure builds behind the wall.

Puddling near the same wall section after every storm points to a specific, fixable entry point.

If you can't remember the last time your sump pump was tested, that's worth addressing before the next storm does it for you.

A wall that bows inward even slightly is responding to soil pressure that isn't going away on its own.

Rising humidity readings in the basement that a dehumidifier can't keep up with.

Rust or corrosion on metal fixtures, HVAC components, or stored tools in the basement.

Our Waterproofing Services in Lexington

From emergency response to permanent structural fixes, here's the full range of work our crews handle in Lexington.

24/7 Emergency Waterproofing experts in Lexington, SC

Emergency Water Extraction & Stabilization

When water is actively rising, extraction comes first — high-capacity pumps clear standing water while we map exactly where it's entering. Extraction is never treated as the finish line — it's the first step toward a lasting repair.

Interior Drain Tile & Sump Systems

This is the most common permanent fix for hydrostatic pressure seepage — proven, code-recognized, and installed without exterior excavation. Every basin includes a check valve, sealed lid, and battery backup so a power outage doesn't undo the fix.

Foundation Crack Injection

Non-structural cracks respond well to polyurethane or epoxy injection depending on whether water is actively present and whether the crack is still moving. Photos and measurements are logged before and after every injection for your records.

Exterior Excavation & Membrane Application

Where the source is grading, a failed footing drain, or membrane failure visible from outside, exterior excavation and a rubberized membrane address the problem at its origin.

Crawl Space Encapsulation & Vapor Control

We size dehumidification equipment to your specific crawl space volume rather than a one-size-fits-all unit.

Sump Pump Installation & Battery Backup

We calculate your pit's actual inflow rate before recommending pump horsepower, since an undersized pump is one of the most common causes of preventable flooding. Backup systems activate automatically the instant the primary loses power or falls behind.

Wall Vapor Barrier & Structural Reinforcement

Dimple-board membrane installed against a foundation wall creates an air gap that channels incidental moisture down to a collection point instead of letting it wick into finished drywall. We explain the engineering rationale before recommending any wall reinforcement work.

Why Lexington, SC Homeowners Choose Arrow Tight Waterproofing

Here's what you're really getting when you call Arrow Tight Waterproofing for Waterproofing in Lexington.

Anyone can put a truck on the road and call it Waterproofing service; what separates a crew worth trusting is what happens once they're standing in front of your foundation.

1

Same-Day Response for Active Intrusion

A basement actively taking on water moves to the front of the schedule — most Lexington, SC service areas see a technician within hours, not days.

2

Written, Itemized Pricing — No Surprises

You'll know the exact cost before work starts — no hourly guessing games, no mid-job upcharges for what a proper inspection should have caught.

3

Diagnosis Before Recommendation, Always

We run a full moisture survey — wall cameras, hydrostatic pressure readings, crack classification — before recommending any specific system.

4

Licensed Specialists, Not General Contractors

Below-grade water intrusion work is a distinct trade, and our technicians are trained and certified specifically in it, not treating it as a side skill.

5

Written Warranty on Every Installed System

Drain tile, sump installations, and crack injections all carry a written warranty against failure at the treated location.

How a Waterproofing Project Actually Works

Four clear steps, no shortcuts skipped along the way — here's what actually happens between your first call and a finished, tested repair.

1

Call & Triage

One call connects you to local dispatch, not a national call center — they'll ask a few questions to understand what you're seeing and prioritize accordingly.

2

On-Site Diagnostic Visit

A technician arrives with moisture meters, a wall camera, and a hydrostatic pressure gauge to identify the actual entry point, not just the visible symptom.

3

Written Quote & Scheduling

Pricing reflects exactly what the diagnostic found, not a generic package.

4

Installation & Verification

Work isn't considered finished until the specific issue that prompted your call is verifiably resolved, tested under real conditions.

Frequently Asked Questions

Answers to the questions homeowners ask most before booking Waterproofing service.

How fast can a Waterproofing technician arrive in Lexington, SC?+
Response time depends on distance from the nearest staged crew, but active leaks are treated as priority dispatch across Lexington, SC.
Do you provide upfront, flat-rate pricing?+
You'll know the full cost before work starts; nothing gets added mid-job without your sign-off first.
Will interior drain tile actually stop the water, or just hide it?+
It's a proven, code-recognized method for managing hydrostatic pressure, not a cosmetic fix that just moves the problem out of sight.
Do I need exterior excavation or can interior work solve it?+
Most seepage from hydrostatic pressure is fully addressable with interior drain tile — excavation is usually reserved for grading or membrane failures visible from outside.
What's the difference between a hairline crack and a structural one?+
A hairline crack is typically under an eighth of an inch and stable — a good candidate for injection. A structural crack shows displacement or is still widening and needs engineering evaluation first.
Is waterproofing work covered by a warranty?+
Warranty terms are included in your written quote before work begins, so there's no ambiguity about what's covered.
How long does a typical installation take?+
Exterior excavation projects take longer, typically several days, depending on wall section length and access.
Do you work on older homes with existing foundation issues?+
Yes, older foundations are some of the most common jobs we handle, and our diagnostic accounts for aging materials and previous repair attempts.
What causes a basement to flood in the first place?+
Hydrostatic pressure from groundwater, poor exterior grading, a failed sump pump, or a combination of all three are the most common causes we diagnose.
Can you help with insurance documentation after a flood?+
We're not public adjusters, but our documentation is formatted to support whatever your insurer's claim process requires.
Do you offer emergency service outside business hours?+
Yes, emergency dispatch operates continuously for active flooding and failed sump pumps, including nights and weekends.
Can you work with my homeowner's insurance claim directly?+
We're not a public adjuster, but we document every job with dated photos and moisture readings formatted for insurance submission.
Do I need to be home during the diagnostic visit?+
Being present lets you see the moisture readings and camera footage firsthand rather than getting a secondhand summary.
What's the first sign I should call about, even if it seems minor?+
Efflorescence — that white chalky residue on concrete — is an easy one to miss but worth addressing early.
Do you offer any kind of maintenance check after installation?+
We're glad to do a post-storm follow-up check after a significant rain event to confirm the system is performing as designed.
Will waterproofing work lower my homeowner's insurance premium?+
It varies by insurer, but a documented drain tile or sump installation is worth mentioning to your agent when you renew.
Do you offer financing for larger projects?+
Financing availability depends on project scope; smaller single-system jobs are usually straightforward flat-rate, while larger combination repairs sometimes qualify for financing.
How do I know if I actually need waterproofing or just better gutters?+
If water is reaching your foundation wall itself, gutters alone usually aren't enough; we'll tell you honestly if a smaller fix like downspout extension would solve it.
Do you guarantee your work in writing, not just verbally?+
We put warranty coverage in writing specifically because verbal promises are hard to enforce months or years later when you actually need them.
What should I do right now if water is actively coming in?+
Call +1-866-476-1348 immediately — dispatch will walk you through basic mitigation steps while routing the nearest available emergency crew to your address.
